Description:

Finding these bright red features confusing?. So confused forgot to do a K & C tests.
Now have been back carried out tests and think they probably are Ophioparma ventosa

Wow! Not come across one like

Wow! Not come across one like this so far - from a quick look at Mike Sutcliffe's thumbnail page: http://www.britishlichens.co.uk/pictureindexcomplete.html
Ophioparma ventosa could be a possible but I can't see from your photo whether the less mature apothecia have white margins......

The LichenIreland site also has a good photo of Ophioparma:

Trouble is I just don't have the experience to know which other similar species there might be - you'll have to go back with the little bottles and test it!

Jenny,

Thanks for that I needed some encouragement , it is the shapes of the apothecia, that I was confused about.
Looking at them I could not decide an overall shape, some seem quite angular some roundish, then accepting they must be bright red apothecia i did look at Ophioparma ventosa but could not see enough detail to decide whether they were lecanorine
Then reading Dobson 'delimited by a rather fimbriate prothallus' ,i.e fringed like a rug, did not understand what I was suppose to see.!
When this snow clears I will go back with my bottles and magnifying glass and have another look

"Looking at them I could not

"Looking at them I could not decide an overall shape, some seem quite angular some roundish,"

In 'The Lichens of Great Britain and Ireland' by Smith et al it says:
"Apothecia 0.4-2.5mm diam, frequent, rounded or irregular, or occasionally becoming sublobulate; thalline exciple +/- well developed, extending under the apothecium, rugose; true exciple level with or slightly raised above the disc, +/- concolorous with the disc or paler ......."

(Need to swallow a dictionary for breakfast!)

When you go back with the little bottles remember it is the medulla, not the cortex, that you'll need to test.

Thanks Jenny.

I did remember to scrap the thallus before testing.
Testing the apothecia i just touched the top with a cotton bud and got a lovely
deep blue colour.
So I am going with Ophioparma ventosa
